Question1

At a certain instant of time, a toy car is travelling at a constant speed of v0 to the right, while a distance D ahead is another toy car starting from rest and travelling to the left with constant acceleration a. The cars are moving along the similar line, directly toward each other. At what time do they collide, in terms of D, v0 and a?

Question2

A car in stop-and-go traffic starts at rest moves forward 19 m in 8.0 seconds, then comes to rest again.

1.) What distance does the car cover in first 4.0 seconds of its motion?
Express the answer using two significant figures.

2.) What distance does the car cover in last 2.0 seconds of its motion?
Express the answer using two significant figures.

3.) What is constant speed V that characterizes a middle portion of its motion?
Express the answer using two significant figures.
